You don't have PM privs just yet. You have to wait a month and put up a certain number of posts before they're automatically activated. It's an anti-spam feature, but I'll activate you as I'm a nice guy.

to get up there im pretty sure you'd have to do a big jump and grab the beams then swing up. didnt want to risk it as if id missed the grab id probably have shot through the floorboards! theyre pretty rotten now

Last time i was there the security had removed the lower ladder but with some careful climbing you can scale the wall to reach the ladders ALthough if you move to energetically in the clock tower it doesnt half wobble You can climb rite out to the very top as well if you desire. Possibly wouldnt reccomend it now tho as it was wobbley as hell back in 2009

went for an explore some weeks ago,wish i had gone when there was still lots of things to look at,tried climbing clock tower ladders,but far to much vandal paint on them.beast of a building,real shame....
